(Reuters) - U.S. Republican presidential candidate Ben Carson raised about $23 million in the last three months of 2015, Politico reported on Wednesday, citing his campaign manager. Carson, a retired neurosurgeon, has fallen in recent weeks from second to fourth place in many national opinion polls and has said he plans a shake-up of his campaign staff. As recently as November, Carson had challenged real-estate billionaire Donald Trump as the front-runner in national polls. He now trails Trump, Texas Senator Ted Cruz and Florida Senator Marco Rubio, according to a Real Clear Politics average of national polls. (Writing by Eric Beech in Washington; Editing by Paul Tait)
